3 targets. A funnel on top of a table with 2 sharp legs.
That is not it, deselect it. It could also be a funnel in a bowl.
That is right, keep it, but deselect the one I said was wrong.
No, that is the wrong one. Click it again and pick the funnel in the bowl again.
Yes, that is correct. But click the wrong one again.
NO! That is wrong. Click it again to deselect. And pick the funnel in the bowl again.
Excellent. Keep that. Pick the person that is leaning back on one hand.
Excellent. Last one resembles a shovel. Or a utensil for serving pie.

Outcome: successful
Speaker comments: Had trouble getting them to deselect a wrong target.
